Pearl CH-70 Cymbal Boom Arm

I think this arm was pretty well put together, and I was satisfied with its adjustability, finding it easy enough to set it up from various stands and mounts. However, one major let down of this cymbal arm is the lack of knurling on the shaft. You will find this on most cymbal boom arms as it helps the stand grip the arm, and you can really tell when it's not there. You are forced to screw it down very tightly in order to stop it from slipping, which is obviously not ideal if you were having to adjust it a lot for example, and even then it had a tendency to slip. It's a really unfortunate oversight on the part of Pearl, which I believe really detracts from what could otherwise have been a great bit of kit.
